Purpose
Techniques used to identify AmpC β-lactamases in SPICE (Serratia, Pseudomonas, indole-positive Proteus, Citrobacter, and Enterobacter) organisms are not yet optimized for the clinical laboratory and are not routinely used. Clinicians are often left with an uncertainty on the choice of antibiotic when a SPICE organism is isolated. The purpose of this study was to evaluate the outcomes of carbapenem versus noncarbapenem regimens in treating bacteremia or urinary tract infection from a SPICE organism in clinical practice.Methods
This single-center, retrospective, cohort study analyzed data from adult patients who had clinical infection with a SPICE organism isolated from blood or urine cultures. Patients were assigned to a carbapenem- or noncarbapenem-treated group. The primary end point was clinical response, defined as a resolution of signs and symptoms of infection at the end of therapy.Findings
A total of 332 patients were assessed, and 145 patients met the inclusion criteria for the study. There were 20 patients who received a carbapenem, while 125 received a noncarbapenem regimen. The percentage of patients who were bacteremic was 46.2%. Clinical response overall was achieved in 80% of patients on a carbapenem versus 90.3% of patients on a noncarbapenem regimen (P = 0.24). The rate of microbiologic cure was 90% in patients on a carbapenem versus 91.2% in patients on a noncarbapenem regimen (P = 1).Implications
In this study in patients treated for infection with a SPICE organism in clinical practice, the rates of clinical response did not differ significantly between the carbapenem and noncarbapenem groups. Current CLSI breakpoints set for SPICE organisms may still be reliable and may not require additional testing for AmpC β-lactamases. 相似文献2.

Purpose
Understanding how sex impacts the efficacy of anticancer agents is a crucial step toward personalized and precision medicine. This review and meta-analysis evaluated sex differences in hazard ratios (HRs) of progression-free survival and overall survival in representative Phase III clinical trials of non–small-cell lung cancer (NSCLC).Methods
Data were extracted from 24 large-scale clinical trials that included 12,000 male and 7000 female patients. The data were examined for HR differences between subgroups by sex, smoking status, and age, and for potential sex–smoking status, sex–age, and sex–drug interactions, during cancer treatment.Findings
Summarized information revealed variations in the influences of sex, smoking status, and age on the efficacy of drugs used for the treatment of NSCLC. The male and female subgroups had different HR values. Smoking status, age, and the percentage of female patients in a treatment group had no influence on the sex HR. The sex difference was supported by a set of data collected from all journals.Implications
The findings from this meta-analysis are important for assessing potential toxicity during drug treatment in both sexes. The outcomes measures of a drug in clinical application should be specified by subpopulation, such as males versus females, as a first step in personalized medicine. 相似文献3.

Purpose
The aim of this study was to evaluate the efficacy and tolerability of rosuvastatin/ezetimibe combination therapy in Korean patients with high cardiovascular risk.Methods
This was a 12-week, randomized, double-blind, placebo-controlled, multicenter study. A total of 337 patients were screened. After a 4-week run-in period, 245 of these patients with high or moderately high risk as defined by the National Cholesterol Education Program Adult Treatment Panel III guidelines were randomly assigned. Patients received 1 of 6 regimens for 8 weeks as follows: (1) rosuvastatin 5 mg, (2) rosuvastatin 5 mg/ezetimibe 10 mg, (3) rosuvastatin 10 mg, (4) rosuvastatin 10 mg/ezetimibe 10 mg, (5) rosuvastatin 20 mg, or (6) rosuvastatin 20 mg/ezetimibe 10 mg. The primary outcome variable was percentage change in the level of LDL-C at week 8 of drug treatment. Secondary outcome variables included percentage changes of other lipid variables and achievement rates of LDL-C targets. Tolerability analyses were also performed.Findings
The percentage change of LDL-C ranged from –45% to –56% (mean, –51%) in the monotherapy groups and from –58% to –63% (mean, –60%) in the combination therapy groups. The percentage change was greater in the pooled combination therapy group than in the counterpart (P < 0.001 for the pooled groups); this difference was more obvious for regimens with a lower statin dose. The percentage reductions of total cholesterol and triglycerides were greater in the combination groups than in the monotherapy groups. The LDL-C target achievement rates were 64% to 87% (mean, 73%) in the monotherapy groups and 87% to 95% (mean, 91%) in the combination groups (P = 0.01 for the pooled groups). The rates were significantly greater in patients receiving the combination therapy than in the monotherapy at lower doses of rosuvastatin. The proportions of patients with various adverse events were not significantly different between the groups.Implications
Rosuvastatin/ezetimibe combination therapy has better efficacy and target achievement rates than rosuvastatin monotherapy in patients with high cardiovascular risk. 相似文献4.

Objective
To identify the precise ABO blood type subgroups with genotyping.Method
We screened ABO blood type from voluntary blood donors in our blood collection center. Samples were first examined with a routine serological method. Samples with ambiguous results were further examined with genotyping to identify ABO subgroups.Results
Two samples identified as AweakB by serology were considered to be A/B and B/B by PCR-SSP. However, the gene sequencing results revealed the precise subgroup to be CisAB01/B101 and CisAB05/B101, respectively.Conclusion
It may be difficult to identify non-typical AB patients with a routine serological method. Genotyping is a more precise method to identify blood subgroups. 相似文献6.
Purpose
Intranasal vaccines are being developed for protection against many different infectious agents. The currently available intranasal live attenuated influenza vaccine (LAIV) is only approved for administration by medical personnel. We conducted a pilot study to investigate the feasibility of training parents to give LAIV to their own children.Methods
Subjects were recruited from several sources: a university-based outpatient clinic, university employee e-mail announcement, and direct referrals from study subjects. After confirming eligibility to receive LAIV, consented parents were trained by viewing a video with the study staff. LAIV was provided in a cooler with instructions to vaccinate within 24 hours. Telephone follow-up was conducted to confirm proper administration and to assess parental attitudes about home administration. At season’s end, immunization registry and hospital records were reviewed to confirm no additional doses were given.Findings
Twenty-seven families with 41 children were enrolled. All participants successfully administered LAIV to their children, and all preferred or strongly preferred home administration to an office visit for getting vaccinated. Two families stated that without this option they would not have otherwise vaccinated their children. Adverse events were minor. All patients had their state vaccine registries accurately updated and none received duplicate doses. Upon review, no reimbursement was received for vaccination.Implications
Home administration of intranasal LAIV was successful and well received. This option could be used in the future for LAIV or other intranasal vaccines as a way to increase vaccination rates and convenience for parents. ClinicalTrials.gov identifier: NCT01938170. 相似文献7.

Purpose
Coronary microvascular dysfunction (CMD) is a common but underdiagnosed cause of chest pain. Literature is scant regarding effective treatments. We explored the effect of ranolazine on coronary flow reserve (CFR) among symptomatic patients with CMD.Methods
This pilot double-blinded randomized controlled trial included emergency department patients with chest pain and CMD admitted to an observation unit between June 2014 and November 2015. Participants were assessed by cardiac Rb-82 positron emission tomography and computed tomography imaging at baseline and 30 days. CMD was defined as CFR <2 corrected for rate pressure product or <2.5 uncorrected, with no evidence of obstructive or nonobstructive coronary artery disease or calcification. Patients with infarction, hypertensive urgency, heart failure, or prescribed QTc-prolonging drugs were excluded. Participants were assigned to ranolazine or placebo in a 2:1 ratio. Primary outcome was change in CFR at 30 days.Findings
We enrolled 31 patients (71% female, mean [SD] age 50 [6] years) with CMD (mean [SD] corrected CFR 1.6 [0.3]). Ranolazine improved CFR at 30 days by 17% (P = 0.005) compared with 0% with placebo (P = 0.67). However, there was no significant difference in the primary outcome as measured by mean change in CFR (0.27 ranolazine compared with 0.06 placebo; 95% CI, ?0.08 to 0.62).Implications
The emergency department offers a unique venue to diagnose CMD with acute symptoms. In an exploratory randomized controlled trial of symptomatic patients with CMD and no coronary artery disease, promising results were seem with ranolazine and CFR improving at 30 days. Large robust clinical trials are needed to verify improvement of CMD in a sex-specific model. ClinicalTrials.gov identifier NCT02052011. 相似文献8.

Background
The addition of extracorporeal photochemotherapy (ECP) to standard immunosuppressive therapy has been suggested to be beneficial in the treatment of recurrent/persistent heart rejection.Methods
We reviewed medical data of heart transplant recipients who received ECP between 2010 and 2016 at our institution.Results
During the study period, eight patients underwent nine ECP courses. The median time from transplant to ECP was 18 months (range 9–54). Indications for ECP were recurrent rejection in 6 patients, persistent rejection in 1 patient and mixed rejection with hemodynamic compromise in 1 patient. Additional criteria for patients’ selection were represented by relevant comorbidities limiting the increase of immunosuppressive therapies. ECP was performed on an outpatient basis in 6 out of 8 patients. The median ECP duration was 12 months (range 1–18). Three out of 8 patients responded to ECP showing negative endomyocardial biopsies at the end of treatment. No additional rejection episodes were observed at their follow up (at 44, 72 and 31 months). Four of 8 patients failed to respond to ECP treatment, one patient has been judged not evaluable. Reduction of immunosuppressive therapies was obtained in all 3 responsive patients but also in 3 patients with a stable grade of rejection. The median duration of the follow up was 26 months (range 6–80). Two patients died at 6 and 21 months after beginning ECP. Survival after ECP was 78.2% at 26 months. No adverse effect or infectious complications associated with ECP were reported.Conclusions
The low response rate (37.5%) in our case series could be partially explained by patient selection, the treated patients representing a high-risk sub-set group. Further studies to provide evidence of a role for ECP in heart rejection treatment or prophylaxis are needed. 相似文献9.

Background
The PLASMIC score was recently described as a convenient tool for predicting ADAMTS13 activity ≤10% in patients with possible thrombotic thrombocytopenic purpura (TTP), while awaiting the results of this send-out test. The purpose of this study was to validate the PLASMIC score at our University Medical Center.Methods
Apheresis records were reviewed from 2008 to 2017 to identify patients who received plasma exchange (PLEX) for suspected TTP. The ADAMTS13 activity and PLASMIC scoring criteria were recorded, and the PLASMIC score was calculated.Results
Of the 41 patients identified, 20 met inclusion criteria, of which 7 patients had ADAMTS13 activity ≤10%. Intermediate and high PLASMIC scores had 100% sensitivity, 46.2% specificity, 50% positive predictive value (PPV), and 100% negative predictive value (NPV).Conclusion
These results are consistent with the original validation study of the PLASMIC score, supporting the efficacy of the PLASMIC score and validating its use at our institution. 相似文献10.

Objectives
Iron is taken into enterocytes at the duodenum via apical divalent metal-ion transporter 1 protein. Besides iron, divalent metal-ion transporter 1 also transports other divalent metals. We aimed to investigate blood heavy metal levels in patients with ineffective erythropoiesis.Methods
Blood levels of heavy metals including Pb, Al, Cd, Cr, Co, Cu, and Zn were measured in patients with thalassemia major (TM), thalassemia intermedia (TI), congenital dyserythropoietic anemia (CDA), and age- and sex-matched healthy controls.Results
Blood samples were obtained from 68 patients (51 patients with TM, 8 with TI, 9 with CDA), and a control group that included 65 volunteers. Patients with TM were found to have lower Al, Pb, and Zn, and higher Cd levels compared with the control group. The patients treated with deferasirox were further analyzed and Pb and Zn levels were found lower compared with the control group.Discussion
Patients with TM had tendency to have elevated levels of plasma cadmium; however, the median level was not at a toxic level. Increased metal-ion transporter 1 activity may cause heavy metal accumulation, but deferasirox chelation may be protective against heavy metals besides iron. 相似文献11.

Background
Scientific literature on blood donation is prevalently concentrated on adults, leaving out adolescents almost completely. While the latter represents “ideal” candidates, they constitute, however, the segment of the population least present among blood donors.Objectives
The present work, composed of two studies, proposes looking into the representations that the adolescents have of blood donation and give voice to the motivations that could persuade them to becoming donors once they reach the legal age for donation. Study I aims to investigate adolescents’ representations about the world of blood donation. Study II aims to investigate a) the underlying motivations for blood donations and b) the relationship between motivations and propensity to donate.Materials/Methods
This paper is based on a mixed methods research design. In Study I, five focus groups were conducted comprising a total of 25 adolescents; for Study II, a self-report questionnaire was administered to 285 adolescents.Results
Study I reveals a lack of information for everything regarding donation, something that produces fear, false beliefs, and an idealized image of the donor.Study II shows that for males, social motivations are fundamental while ego-protective motivations are deterrents, and that females are most impacted by understanding.Conclusion
The study shows how the adolescent population cannot be recruited in the same way as adults, and presents valuable points for those who finalize advertising campaigns for donor recruitment recruitment. 相似文献12.

Purpose
A literature review of multiple clinical studies on mixing additives to improve pharmacologic limitation of local anesthetics during peripheral nerve blockade revealed inconsistency in success rates and various adverse effects. Animal research on dexmedetomidine as an adjuvant on the other hand has promising results, with evidence of minimum unwanted results. This randomized, double-blinded, contrastable observational study examined the efficacy of adding dexmedetomidine to a mixture of lidocaine plus ropivacaine during popliteal sciatic nerve blockade (PSNB).Methods
Sixty patients undergoing varicose saphenous vein resection using ultrasonography-guided PSNB along with femoral and obturator nerve blocks as surgical anesthesia were enrolled. All received standardized femoral and obturator nerve blocks, and the PSNB group was randomized to receive either 0.5 mL (50 µg) of dexmedetomidine (DL group) or 0.5 mL of saline (SL group) together with 2% lidocaine (9.5 mL) plus 0.75% ropovacaine (10 mL). Sensory onset and duration of lateral sural cutaneous nerve, sural nerve, superficial peroneal nerve, deep peroneal nerve, lateral plantar nerve, and medial plantar nerve were recorded. Motor onset and duration of tibial nerve and common peroneal nerve were also examined.Findings
Sensory onset of sural nerve, superficial peroneal nerve, lateral plantar nerve, and medial plantar nerve was significantly quicker in the DL group than in the SL group (P < 0.05). Sensory onset of lateral sural cutaneous nerve and deep peroneal nerve was not statistically different between the groups (P > 0.05). Motor onset of tibial nerve and common peroneal nerve was faster in the DL group than in in the SL group (P < 0.05). Duration of both sensory and motor blockade was significantly longer in the DL group than in the SL group (P < 0.05).Implications
Perineural dexmedetomidine added to lidocaine and ropivacaine enhanced efficacy of popliteal approach to sciatic nerve blockade with faster onset and longer duration. 相似文献13.
Background
Ideally, high-stakes examinations assess 1 dimension of medical knowledge to produce precise estimates of a candidate’s performance. It has not been reported whether the American Board of Physical Medicine and Rehabilitation Part 1 Certification Examination (ABPMR-CE-1) is unidimensional or not.Objective
To examine the ABPMR-CE-1 to measure how many dimensions it assesses.Design
Retrospective observational study.Setting
We assessed examination results from the 2015 ABPMR-CE-1.Participants
A total of 489 deidentified candidates taking the 2015 ABPMR-CE-1.Methods
A 1-parameter Item Response Theory (IRT) measurement model was utilized. A Principal Components Analysis (PCA) of standardized residual correlations was used to detect multidimensionality.Main Outcome Measure
Number of primary dimensions reflected in the 325 test questions.Results
The results of the dimensionality analysis indicated that the ABPMR-CE-1 examination is highly unidimensional from a psychometric perspective. Expert content review of the substantive content of small contrasting clusters of questions provided additional assurance of the unidimensional nature of the examination.Conclusions
The ABPMR-CE-1 appears indeed to measure a single construct, which suggests a sound structure of the examination. It closely approximates the assumption of statistical unidimensionality.Level of Evidence

Background
Stroke is a primary cause of death and disability in upper-middle–income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region.Objective
To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia.Design
Cross-sectional study.Setting
The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia.Participants
Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50).Methods
Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnairesMain Outcome Measurements
Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke.Results
Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls.Conclusions
This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues.Level of Evidence

Background
Washed platelet concentrate (WPC) is prepared manually in general, but automated preparation is desirable to minimize variation in the WPC quality and enhance WPC production. Recently, the software was improved for an automated cell processor (ACP) to control all processes of WPC preparation. M-sol and BRS-A, which are mixtures of medical solutions, are widely used for WPC preparation with a manual method in Japan. In this study, we prepared WPC suspended in M-sol (WPC-M) or BRS-A (WPC-B) with the ACP, and compared their in vitro properties during 7-day storage.Study design and methods
PC was divided into two equal aliquots for WPC-M and WPC-B. A divided PC, medical solutions and disposable materials were set in the ACP, and it was started to prepare WPC-M or WPC-B on Day 0. Prepared WPC was stored on a flatbed shaker until Day 7.Results
The pH of WPC-M and WPC-B was maintained above 6.8 during the 7-day storage. The differences in aggregation (%), HSR (%), P-selectin expression, GPIbα expression, and phosphatidylserine expression between WPC-M and WPC-B were minimal until Day 3.Conclusion
The in vitro properties of WPC-B are not markedly different from those of WPC-M until Day 3. 相似文献16.

Background
A significant proportion of burn injury patients are admitted to inpatient rehabilitation facilities (IRFs). There is increasing interest in the use of functional variables, such as cognition, in predicting IRF outcomes. Cognitive impairment is an important cause of disability in the burn injury population, yet its relationship to IRF outcomes has not been studied.Objective
To assess how cognitive function affects rehabilitation outcomes in the burn injury population.Design
Retrospective study.Setting
Inpatient rehabilitation facilities in the United States.Participants
A total of 5347 adults admitted to an IRF with burn injury between 2002 and 2011.Methods or Interventions
Multivariable regression was used to model rehabilitation outcome measures, using the cognitive domain of the Functional Independence Measure (FIM) instrument as the independent variable and controlling for demographic, medical, and facility covariates.Main Outcome Measurements
FIM total gain, readmission to an acute care setting at any time during inpatient rehabilitation, readmission to an acute care setting in the first 3 days of IRF admission, rate of discharge to the community setting, and length of stay efficiency.Results
Cognitive FIM total at admission was a significant predictor of FIM total gain, length of stay efficiency, and acute readmission at 3 days (P < .05). Cognitive FIM total scores did not have an impact on acute care readmission rate or discharge to the community setting.Conclusions
Cognitive status may be an important predictor of rehabilitation outcomes in the burn injury population. Future work is needed to further examine the impact of specific cognitive interventions on rehabilitation outcomes in this population.Level of Evidence

Introduction
Development of technologies to reduce transfusion risks of infectious diseases is a major characteristic of hemotherapy. Thus, each donation undergoes clinical and serological screening tests to ensure the donated blood do not offer risks to the receiver.Objective
Evaluate the prevalence of positive serology in blood donations rejected by Hemobanco (Curitiba – PR) in the period ranging from January 2003 to December 2012.Methodology
During the period studied, we observed the total number of donations and its division according to gender. We also analyzed the number of rejected donations due to seropositivity, considering the diseases investigated routinely in blood banks in Brazil, and the frequency of discards according to age groups.Results
Within the period studied, 399,280 donations were performed. 62.0% donors were male. Comparing 2003 to 2012, we noticed a significant decrease of discards, from 10.2% to 5.0%, respectively. There was a reduction of seropositivity for HIV, HBsAg and anti-HBc and an increase for Chagas Disease, hepatitis C, syphilis and HTLV. The age group with the highest prevalence for discards changed: it used to be the 40–59 years old group in 2003, and became the 20–39 years old group in 2012.Conclusion
There was an increase in the number of donations in Hemobanco and a decrease in total discards due to seropositive donations. Most donors were male. The most prevalent cause of discards only amongst seropositive donation discards is seropositivity for anti-HBc. There was a significant increase of donors aged between 20 and 39 years old. 相似文献18.

Purpose
Opioid-induced constipation (OIC) is a bothersome side effect of opioid use for the management of noncancer pain, affecting patients’ health-related quality of life and chronic-pain management. The objective of this study was to examine the relationship between changes in the frequency of spontaneous bowel movements (SBMs) and changes in patient-reported outcomes (PROs) among patients with OIC treated with naloxegol.Methods
Post hoc analyses were conducted using pooled data from two Phase III 12-week, placebo-controlled trials of naloxegol for the treatment of OIC (NCT01309841 and NCT01323790). Patients completed the Patient Assessment of Constipation–Quality of Life (PAC-QOL) and PAC–Symptoms (PAC-SYM) at each study visit, and the Straining Scale and Bristol Stool Scale (BSS) with each bowel movement for the study duration. Four subgroups were created based on improvements from baseline in mean frequency of SBMs per week: 0 or worse (no change), +1 SBM, +2 SBMs, and +≥3 SBMs. Spearman correlations assessed the association between mean SBM changes from baseline and mean changes from baseline in PROs; analysis of covariance was used to compare changes from baseline.Findings
A total of 1337 patients with mean (SD) age of 52.2 (11.0) years were included in this analysis. The patient population was predominantly white (79.0%) and female (62.4%). At baseline, mean SBM frequency was 1.4 (1.0) per week. At study end, all 4 SBM-change subgroups experienced improvements in PAC-QOL, PAC-SYM, Straining Scale, and BSS scores, and these changes were significantly correlated with mean changes from baseline in SBMs per week. The subgroup of patients with an increase in SBMs of ≥3 per week experienced the greatest improvements in PROs.Implications
In these patients with OIC, an improvement in the frequency of SBMs by ≥3 per week was associated with consistent improvements in PROs, providing support for the use of improvements in SBMs as a clinical outcome surrogate for managing patients with OIC. Further research is needed to determine a threshold for change in SBMs that is clinically meaningful in both research and clinical settings. A key limitation was the post hoc nature of the study, which was not powered prospectively to examine these relationships. 相似文献19.
